I recently bought the Milwaukee cordless pole saw since I use other Milwaukee tools at work. It has really surprised me. No problem on 8" oak. Maybe a little slower than a gas powered Stihl, but no choke, premix, pull cords, ethanol, etc. It is basically a powerhead which accepts other attachments. Acme Tool had a promo where you got an extra attachment for free, so I got 2 saws and a powerhead.
